What Is Percentage Share in Table DI?
The relevant total may be the total of a row, column, category or the entire table, depending on the question. For example, if a department records 80 units out of a total of 400 units, its percentage share is (80 ÷ 400) × 100 = 20%. The sum of all shares based on the same total is 100%.

Percentage Share in Table DI Formula & Tricks
Important Formulas
Use the value named in the question as the numerator and the applicable row, column or grand total as the denominator.
Use this when each entry is compared with the total of its own row.
Use this when each entry is compared with the total of its own column.
Subtract the two percentage shares when the question asks how many percentage points one share exceeds another.
Use this when the question asks for the percentage increase in a share, not merely the difference between two shares.
Quick Tricks
Reduce the fraction formed by Required Value ÷ Total before converting it to a percentage. This avoids unnecessary decimal calculations.
If all categories use the same total, the share of the remaining categories is 100% minus the known share.
A percentage share may use a row total, column total or grand total. Do not use the grand total automatically.
Percentage Share in Table DI Concepts
Calculating Share from a Table Total
First identify the value asked for. Next calculate the total specified by the question. Apply Percentage Share = (Value ÷ Total) × 100. Keep the denominator and numerator from the same basis.
Row-Wise and Column-Wise Share
For a cell at the intersection of a category and a year, select the denominator according to the wording. A row percentage describes the cell's contribution to that category total; a column percentage describes its contribution to that year's total.
Percentage Share Using a Grand Total
The grand total is obtained by adding all relevant entries, or by adding row totals or column totals once. Do not add both row totals and column totals, because that counts every entry twice.
Comparing Two Percentage Shares
If one share is 40% and another is 25%, their difference is 15 percentage points. The percentage by which the first exceeds the second is (15 ÷ 25) × 100 = 60%, because the second share is the base.

| C | 240 | 40% |
| D | 60 | 10% |

Percentage Share in Table DI Revision Points
Use the relevant total as the denominator and express the resulting fraction as a percentage.
- Percentage Share = (Required Value ÷ Relevant Total) × 100.
- Use a row total for row-wise share and a column total for column-wise share.
- Use the grand total only when the question refers to the complete table.
- Shares calculated from the same total add up to 100%.
- A percentage-point difference is direct subtraction; percentage change uses the original share as the denominator.
- Do not count values twice when calculating a grand total from row totals or column totals.
Percentage Share in Table DI FAQs
What is the percentage share in Table DI formula?
Percentage Share = (Required Value ÷ Relevant Total) × 100. The relevant total may be a row total, column total or grand total.
How do you find the percentage share of 90 out of 360?
Percentage share = (90 ÷ 360) × 100 = 25%.
What is the percentage share of category B in the sample table?
Category B has value 180 and the grand total is 600. Its share is (180 ÷ 600) × 100 = 30%.
What is the difference between percentage share and percentage increase?
Percentage share compares a part with a total. Percentage increase compares the change in a value with its original value: ((New − Old) ÷ Old) × 100.
If a row contains 45 out of a row total of 180, what is its row-wise share?
Row-wise share = (45 ÷ 180) × 100 = 25%.
How do you calculate column-wise percentage share?
Divide the cell value by the total of its column and multiply by 100. For example, 50 out of a column total of 200 gives 25%.
